Doravirine (MK-1439) is a nonnucleoside inhibitor of HIV reverse transcriptase (NNRTI). It displays excellent activities against not only WT viruses but also a broader panel of NNRTI-resistant viruses. Doravirine is a prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV infection in adults who have never taken HIV medicines before. Doravirine is always used in combination with other HIV medicines.

Lofexidine is newly FDA approved in the United States under the brand name LUCEMYRA for the treatment of opioid withdrawal symptoms in adults. Lofexidine acts as an agonist to α2 adrenergic receptors. These receptors inhibit adenylyl cyclase activity, leading to the inhibition of the second messenger, cyclic adenosine monophosphate (cAMP). The inhibition of cAMP leads to potassium efflux through calcium-activated channels, blocking calcium ions from entering the nerve terminal, resulting in suppression of neural firing, inhibition of norepinephrine release. Lofexidine replaces the opioid-driven inhibition of cAMP production and moderating the symptoms of opioid withdrawal.
Cannabidiol is the major nonpsychoactive ingredient in cannabis. Cannabidiol demonstrates a range of effects that may be therapeutically useful, including anti-seizure, antioxidant, neuroprotective, anti-inflammatory, analgesic, anti-tumor, anti-psychotic, and anti-anxiety properties. Exact mechanism of action of cannabidiol is not known, but may include effects on the orphan G-protein-coupled receptor GPR55; the transient receptor potential of vanilloid type-1 channel; the 5-HT1a receptor; and the α3 glycine receptors. GW Pharmaceuticals successfully developed the world’s first prescription medicine derived from the cannabis plant, Sativex® (buccal spray containing delta-9-tetrahydrocannabinol and cannabidiol) now approved in over 29 countries outside of the United States for the treatment of spasticity due to Multiple Sclerosis. GW Pharmaceuticals is developing Epidiolex® (a liquid formulation of pure plant-derived cannabidiol) for certain rare and severe early-onset, drug-resistant epilepsy syndromes.

Migalastat (Galafold)-a small molecule drug developed by Amicus Therapeutics that restores the activity of specific mutant forms of α-galactosidase-has been approved for the treatment of Fabry disease in the EU in patients with amenable mutations. Migalastat attaches to certain unstable forms of alpha-galactosidase A, stabilising the enzyme. This allows the enzyme to be transported into areas of the cell where it can break down GL-3. Under the trade name Galafold (formerly known as Amigal), Migalastat is used to treat patients aged 16 years or over with Fabry disease. Because the number of patients with Fabry disease is low, the disease is considered ‘rare’, and the US Food and Drug Administration (FDA) assigned Galafold orphan drug status in 2004, and the European Committee for Medicinal Products for Human Use (CHMP) followed in 2006.
Binimetinib (MEK162) is an oral small-molecule with potential antineoplastic activity. It is a selective mitogen-activated protein kinase 1 and 2 (MEK1/2) inhibitor, a key protein kinase in the RAS/RAF/MEK/ERK pathway, which regulates several key cellular activities including proliferation, differentiation, migration, survival and angiogenesis. Inappropriate activation of this pathway has been shown to occur in many cancers, in particular through mutations in BRAF, KRAS and NRAS. MEK162 at 6 mg/kg, BID combined with BEZ235 (dual PI3K/mTOR inhibitor) resulted in a significant reduction of tumor growth in immunodeficient mice injected with MCF7 cells. There are three ongoing Phase 3 trials with binimetinib in advanced cancer patients: NEMO (NRAS-mutant melanoma), COLUMBUS (encorafenib in combination with binimetinib in BRAF-mutant melanoma) and BEACON CRC (encorafenib, binimetinib and cetuximab in BRAF-mutant colorectal cancer).
Tezacaftor (VX-661) is an investigational compound developed by Vertex Pharmaceuticals to treat cystic fibrosis (CF). It is an oral corrector of the CF transmembrane regulator (CFTR) and is similar to lumacaftor, another N-aryl-1-(2,2-difluoro-1,3-benzodioxol-5-yl)cyclopropanecarboxamide derivative developed by Vertex. Cystic fibrosis is caused by defects in CFTR gene, which encodes an epithelial chloride channel. The most common mutant Δ508CFTR is a misfolded protein that does not reach the cell membrane. VX-661 corrects trafficking of Δ508CFTR and partially restores chloride channel activity. In vitro, a combination of VX-661 and ivacaftor, an FDA approved in 2012 CFTR potentiator which increases the time the CFTR channel is open, allowing chloride ions to flow through the CFTR proteins on the surface of epithelial cells, resulted in greater CFTR activity compared with VX-661 alone. In February 2012, a phase 2, double-blind, placebo-controlled study of VX-661 was initiated in CF patients who were homozygous or heterozygous for the F508del mutation. There is an ongoing Vertex Phase 3 development program of VX-661 in combination with ivacaftor which includes four studies on CF patients 1) with two copies of the F508del mutation, 2) one copy of the F508del mutation and a second mutation that results in residual CFTR function, 3) one copy of the F508del mutation and a second mutation that results in residual CFTR function gating defect in the CFTR protein and 4) one copy of the F508del mutation and a second mutation that results in minimal CFTR function.
Bictegravir is a component of the fixed-dose combination product bictegravir/emtricitabine/tenofovir alafenamide (BIKTARVY®), which received marketing approval for the treatment of human immunodeficiency virus (HIV) infection by the U.S. Food and Drug Administration in February 2018. Bictegravir inhibits the strand transfer activity of HIV-1 integrase, an HIV-1 encoded enzyme that is required for viral replication. Inhibition of integrase prevents the integration of linear HIV-1 DNA into host genomic DNA, blocking the formation of the HIV-1 provirus and propagation of the virus.
Talazoparib (BMN 673) demonstrates excellent potency, inhibiting PARP1 and PARP2 enzyme activity. It inhibits PARP-mediated PARylation in a whole-cell assay and prevents proliferation of cancer cells carrying mutant BRCA1/2. Talazoparib is orally available, displaying favorable pharmacokinetic properties and remarkable antitumor efficacy in the BRCA1 mutant MX-1 breast cancer xenograft model following oral administration as a single-agent or in combination with chemotherapy agents such as temozolomide and cisplatin. Medivation (a subsidiary of Pfizer) is developing talazoparib (MDV 3800, formerly BMN 673 and LT 673) for the treatment of genetically defined cancers. On October 16, 2018, the FDA approved talazoparib (TALZENNA, Pfizer Inc.) for patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm), HER2‑negative locally advanced or metastatic breast cancer.
Encorafenib, also known as BRAFTOVI or LGX818, is an orally available mutated BRaf V600E inhibitor with potential antineoplastic activity, which was developed by Novartis. LGX818 possesses selective anti-proliferative and apoptotic activity in cells expressing BRAFV600E. In the A375 (BRAFV600E) human melanoma cell line LGX818 suppresses phospho-ERK (EC50 = 3 nM) leading to potent inhibition of proliferation (EC50 = 4 nM). No significant activity was observed against a panel of 100 kinases (IC50 > 900 nM) and LGX818 did not inhibit proliferation of > 400 cell lines expressing wild-type BRAF. On June 27, 2018, the Food and Drug Administration approved encorafenib and Binimetinib (BRAFTOVI and MEKTOVI, Array BioPharma Inc.) in combination for patients with unresectable or metastatic melanoma with a BRAF V600E or V600K mutation, as detected by an FDA-approved test. Encorafenib and binimetinib target two different kinases in the RAS/RAF/MEK/ERK pathway. Compared with either drug alone, co-administration of encorafenib and binimetinib result in greater anti-proliferative activity in vitro in BRAF mutation-positive cell lines and greater anti-tumor activity with respect to tumor growth inhibition in BRAF V600E mutant human melanoma xenograft studies in mice. In addition to the above, the combination of encorafenib and binimetinib acted to delay the emergence of resistance in BRAF V600E mutant human melanoma xenografts in mice compared with the administration of either drug alone. Encorafenib is in phase III for Metastatic Colorectal Cancer and in phase II for Relapsed or Refractory Multiple Myeloma.
Lutetium Lu 177 dotatate binds to somatostatin receptors with highest affinity for subtype 2 receptors (SSRT2). Upon binding to somatostatin receptor expressing cells, including malignant somatostatin receptor-positive tumors, the compound is internalized. The beta emission from Lu 177 induces cellular damage by formation of free radicals in somatostatin receptor-positive cells and in neighboring cells. LUTATHERA® (lutetium Lu 177 dotatate) is indicated for the treatment of somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors (GEP-NETs), including foregut, midgut, and hindgut neuroendocrine tumors in adults.
